Larry,

I wouldn't anticipate much in the way of power after reading the specifications on the 530 system. Granted, there is 70 watts available, but keep in mind that most of the satellites are just 7.5 watts each--not much there.

If you decide to purchase the 530 system, I would urge you to buy it from someone with a liberal return policy--even if you have to pay a little more. Could save lots of greif in the long run.
